Step by step tutorial on how to use PARI/GP development version in Sage
This tutorial explains how to use a PARI/GP development version inside Sage.
Prerequisites

- You need to use a version of Sage compiled from source located at $SAGE_ROOT
Procedure
Download the script pari_sage.sh
Do
$ cd $PARI_ROOT $ sage -sh # starts Sage environment $ source pari_build.sh # reading pari_build.sh $ pari_set_environment # setting properly environment variables for compilation $ pari_build # building pari $ pari_install # installing pari
Recompile cysignals
$ sage -f cysignals # recompile cysignals (to be linked correctly against pari)

$ sage -pip install git+https://github.com/defeo/cypari2
Recompile what needs to be
